Clinico-Morphological Features and Immunohistochemical Profile of a Rare Case of Three Synchronous Primary Malignancies in the Female Genital Tract.

(1) Background: Synchronous tumors are defined as tumors that occur at the same time, appearing within 2 months, according to the Surveillance Epidemiology and End Results Program, with a frequency of tertiary tumors of 0.5%. The purpose of this presentation is to report a case of three synchronous tumors of the female genital tract, given the fact that it represents a challenge both therapeutically and in demonstrating that the malignant lesions are completely different from each other. (2) Methods: We report the case of a 45 year-old patient diagnosed with three synchronous tumors developed in the genital tract: clear-cell ovarian carcinoma, uterine endometrioid adenocarcinoma, and cervical adenosquamous carcinoma. (3) Results: Total hysterectomy with bilateral anexectomy was performed and accompanied by a biopsy of the greater omentum. The evolution of the patient was favorable during chemotherapy, but she died two weeks after the completion of this treatment, from a cause secondary to the adverse effects determined by it, namely, severe thrombopenia which caused a massive lower digestive hemorrhage. (4) Conclusions: This case demonstrates the maximum importance of the involvement of adjuvant diagnostic techniques, especially when it comes to a diagnostic challenge with direct implications in the subsequent therapy of the patient.
